Bug description:
There is an error observed when Ubuntu is configured to perform
authentication via pam_vas (Vintela Authentication Services by Dell)
in a disconnected mode (using cached authentication).
Steps to reproduce:
1. Configure pam_vas client authenticating to a remote server.
2. Perform authentication to cache the credentials.
3. Disconnect from the network where the server is reachable (to force using cached information).
4. Perform an action requiring polkit authentication.
Expected result:
Authentication succeeds accompanied by the following message "You have logged in using cached account information. Some network services will be unavailable".
Actual result:
Authentication fails accompanied by the following message "You have logged in using cached account information. Some network services will be unavailable".
Probable cause:
The PolkitAgentSession part of polkit is designed to interpret only 1-line output, while interaction with pam_vas in the above scenario triggers helper to produce the following 2-line output:
PAM_TEXT_INFO You have logged in using cached account information. Some network services
will be unavailable.
The 'will be unavailable.' part is interpreted as an unknown message
and causes failed authorization.
